N and d are both numbers of thousands of dollars.
Thus, if n = 1, that means $1000.
Here n = d + 0.4.
Note that in C, n+0.04=n is completely wrong.
Similarly, in D, d = 0.04 = n is completely wrong.
The "combined profit amount" for Nov. and Dec. is n + d = 3.15.
Only A matches this info. Your answer is A.

☞ First, 0.40 is the same as 40/100.
But we are not done.
<u>Now, doing this you need to find the GCF (Greatest common factor) of 40, 100.</u>
2 x 2 x 5 = 20.
☞ So our GCF is 20.
Divide both the numerator and the denominator by the GCF.
40 ÷ 20 / 100 ÷ 20.
<h2>Simplify to get ☞ 2/5.</h2><h2>▬▬ι══════════════ι▬▬</h2>
Best of luck on your assignment!
